Under certain conditions, as in the association of coating apparatuswith such a machine as that referred to above, there are createdproblems as to compactness and convenience of arrangement, the supply ofconsiderable quantities of the adhesive without waste, and themaintenance of this adhesive in proper condition for application, whichit is thev object of this invention to solve. Suchobject is attained byassociating with an adhesive-applying mechanism, holding means or tablesfor the work-portions, which ing shown, though' there may be utility inthe employment of but one. A table at one side of the applying mechanismmay move toward and from said mechanism, which latter consists, asillustrated, of an applying roll and a pressure-roll, to deliverwork-portions thereto. lin the present embodiment of the invention, thismovement is in twodirections, as in a plane through the bite of therolls and toward and from said plane. The latter movement facilitatesthe receipt of the work, as from a container, while the former eiectsits delivery for the coating operation. A work-holding table at theopposite side of the applying mechanism similarly moves to- Ward andfrom it, advantageously receiving the coated work, and then, in itsoutward position,lfreeing said work from the applymg mechanism forconvenient transfer. The preferable manner of supplying adhesive is froma receptacle by a distributing device cooperating with the applyingmechanism, as a head or nozzle extending along the applying roll. Th'esupply is controllable, as by a valve movable in the head. To prevent,dooding and to minimize drip, there is providedy means to render theadhesive-applying means leffective in timed relation with theworkdellvermg means. This may be accomplished v structed flow of theadhesivel is obtained by heating elements with which it contacts, forexample at the receptacle, at the head, and along the intermediate pipesor connections. A desirable manner of applying heat to theadhesive-receptacle is by means of a surrounding water-tank. Anadhesive-conduit leads from the receptacle to the applying means, and,since the receptacle is preferably removable fork filling, there is aseal furnished between the conduit and receptacle, with means forapplying pressure to the receptacle to render this seal effective. Toretain the contents of the receptacle against discharge during suchremoval, a valve may be provlded at the opening oi? the conduit, with ahandle extending through thereceptacle into proximity with its top andby which it may be conveniently closed and opened.

The accompanying drawings .illustrate a particular embodiment of theinvention,

At 58 (see particularly Fig. 1) appears a magazine or container adaptedto contain a stack of insole or other blanks B Fig.. 2) to,

be operated upon, and from which they are delivered one by one under thecontrol of separator devices 274 upon a feed or delivering table 616.This table is movable both vertically and horizontally, and advances theblanks endwise into the grip of co-operating upper and lower rolls 618and 620 of a coating mechanism, the lower roll 620 being adapted toapply cement or other adhesive to the under face of each blank while theroll 618 puts ressure upon the work. The blanks are ed by the rolls 618and 620 across the top of a horizontally slidable receiving table 622,which advances them into position to be transferred for furtheroperations upon them.

The table 616, which receives the composite blanks from the magazine 58,is shown as -rectangular in form, and is supported and adapted to slidehorizontally upon rollers 624, which are arranged in pairs'on the outersides of two vertically disposed parallel side frames 626 projectingfrom a vertically slidable carriage 528. The pairs of rollers 624 arereceived in horizontal grooves 628 formed in the inner sides of twoparallel anges 629 depending from the opposite longitudinal edges of thetable 616.

The carriage 528 is adapted to be raised to elevate the feed-table 616to a position immediately below the bottom of the stack in the magazine,so that, when the lowermost blank is released, it will not be ermittedto fall through any substantial c istance, but will be received directlyupon the feed-table, thus avoiding possible endwise displacement. Topermit the carriage 528 to be raised and lowered, it is provided withtwo vertical ribs 630, which project at the outer sides of the framemembers 626, and each rib 630 is adapted to ride upon the peripheries ofrollers 632, which are severally carried by upper and lower brackets 634and 636, and are arranged to engage the opposite faces of the ribs. Theouter edge face of each rib 630 is guided by a pair of rollers 638, also.carried by the brackets 634 and 636 (Fig. 3)

both secured to a single support 640. The weight of the carriage 528 andthe various arts mounted thereon is counter-balanced y springs 642secured at their lower ends to the carriage and. at their upper ends tothe bracket 634.

In order that the carriage 528 may be reciprocatedverticallyto bring thefeed-table 616 to the proper elevation to receive a blank from themagazine, and then to lower`the table to the level of the top of thecement-roll 620, a rack-bar 646 is secured to the carriage, and is enaged by a segment 648 carried by a rock-sha t 650 journaled in a bearingcarried by the support 640. An arm 652 is fastened upon the rock-shaft65() at the opposite end from the segment 648, and this arm is connectedby means of a link 654 with one end of a cam-lever 656 fulcruxned at658. The cam-lever 656 carries a roll 660, which is received in acam-groove 661 in the outer side of a cam-disk 662 {ixed to a horizontalshaft 664 journaled in hearings on the frame and continuously drivenduring the. operation of the apparatus. The cam-disk (262 is rotated incorrect time-relation with the associated movable elements, the grooveengaged by the roll 660 being so designed as to cause a singlereciprocation of the carriage 528 for each operating cycle of theapparatus.

' The feed-table 616 is so constructed that it does not extend beneaththe extreme toc-end portion of the stack of blanks. Thus, when a blankis received upon the table 616, its

toe will project somewhat beyond the forward end of the table, asindicated at b in Fig. 2. After the table 616 has been lowered into th`position in which it appears in Fig. 2, so that the blank is supportedat the proper level to be introduced between the rolls 618 and 620. saidtable is caused to slide horizontally upon the rollers 624 to presentthe toe-end of the blank to the grip of said rolls.

The means for horizontally reciprocatingr the feed-table 616 comprises asegment 674. which engages a rack-bar 676 secured to the under side ofthe table. The lower portion of the segment 674 is pinned to arock-shaft 678 journaled in the frame members 626.` To actuate therock-shaft 678, an arm 680, which is secured to the rock-shaft, isconnected by means of a link 682 to one end of the upwardly extendingarm of a bell-crank lever 684 fulcrumed at 686. The other arm of thebell-v crank lever carries a cam-roll 688, which rides in a cam-groove690 in the disk 662 at the opposite side from the groove 661 engaged bythe roll 660. The cam-groove 690 is designed to reciprocate thefeed-table 616 horizontally, once for each rotation of the. disk 662.The link 682 is connected with the arm 680 by means of a pivot-studwhich extends through a longitudinal slot 691 in the arm and isadjustably secured thereto. The slot 691 normally extends at such anangle with respect to the pivotal connection between the. opposite endof the link 682 and the cam-lever 684 that, by shifting the position ofthe pirotstud-in the slot, the table may be adjusted toward and from therolls 618 and 620, in accordance with the length of the sole-blanksbeing operated upon.

The vertical reciprocating movements of ion L, rotate in bearingssupported b the blank-sewratin devices throu hconnections 693. hen t eseparator evices act to release a blank from the bottom of the stack,the feed-table 616 occupies its uppermost position, removed from therolls 618 and 620. After a blank has been deposited upon the table, thisdescends, and is advanved to present the projecting toe-portion to thegrip of the rolls. These rolls are mounted to a lpair of arms 704 and 706 rising vertica lv from the bracket 634, and are continuous y actuatedthroughout the operation of the machine in directions to feed the blankspresented thereto from the table' 616 between the .rolls and rupon thereceiving table 622.

The lower or cement-applying ro1l.620 comprises a cylindrical shell,closed at its opposite ends and provided with a serie's of annular ribs7 08 arranged parallel to each other and equally spaced a art across theexternal cylindrical surface o the roll. Intersecting the annular ribs 708 are a series of transverse ribs 710, which are equally spaced apartin parallel relation to each other, The ribs 708 and 710 provide aseries of square, shallow pockets 712 adapted to contain (ement which isto be applied to the blanks as they pass over the top of the roll. 011eend of the roll 620 is supported upon the inwardly projecting extremityof a short horizontaldriving shaft 714 (Fig. 3), which is journaled inspaced-apart bearings 716 in the arm 704. T'o connect the roll 620 torotate with the driving shaft 714, a collar 718 is pinned to the drivingshaft and is provided with tongues 720 upon the inner end face of thecollar at opposite sides of the shaft, these tongues being adapted toenter corresponding grooves formed in a hub 722 on the roll 620. 'At theopposite end, the roll 620 is j ourn aled upon the inwardly projectingend of a horizontal stud 724, which is supported in the arm 706 and isaxially alined with the driving shaft 714. To permit removal of the roll620 for cleaning or replacement, the stud 724 is mounted to slide on thearm 7 06, so that it may be withdrawn from the roll, and the supporti-ngarm 706 is hinged upon a vertical pintle 726 (Fig. 2) carried by thebracket 634,

n to adapt it to be swung outwardly away from the arm 7 04. The stud 724is provided with a nurled head, by means of which' it may be moved in orout in its bearing on the arm 706. When the stud 7 24 has been withdrawnfrom the roll 620, and the arm 706 has been swung outwardly, the roll620 may be readily removed from thel driving shaft 714. bayonet-jointconnection 728 (Fig. 3)l between the stud .724 and the arm 7 06 isprovided for limiting the outward sliding movement. of the stud in itsbearing, and for permitting the stud to be locked in the inner orroll-supporting position.

The upper roll 618, which is shown as of the same diameter as the lowerroll, also comprises a cylindrical shell closed 'at its opposite ends.The external cylindricalsurface of the roll 618 is provided with aseries of annular ribs 732 arranged in parallel relation to each other,and opposed to the corresponding annular ribs 708 of the lowerl roll.

The roll 618 is supported at ,one extremity upon the inwardly projectingend ofv a short horizontal shaft 734,`which is journaled in spaced-apartbearing-sleeves 736 Anormally resting upon the lower end walls of a pair'of vvertical slots 738 formed in the upper `portions of the arms 704.The shaft 734 is driven from .the shaft 714 through intermeshingspur-gears 740, one of whlch is secured to each of said shafts betweenthe bearings thereof. The roll 618 is connected to turn with the shaft734 by means of a collar 742 pinned to the shaft and provided withtongues 744, which project into corres nding grooves in a hub 746 on theroll. t the opposite end of the roll 618, a. hub 748 is journaled uponthe inwardly projecting end of a horizontal stud 750, `adapted to slidelongitudinally within a sleeve 7 52. The sleeve 752 is located within avertical slot 754 at the upper extremity of the arm 706 andnormally'resting upon the lower end wall of saidfslot. Annular flangesl756, `at the opposite'e'nds of the sleeve 7 52, prevent its longitudinaldisplacement by engagement with adjacent faces of the arm 706. With thisarrangement', the upper roll 618 is'spaced from the lower roll 620 adistance somewhat -less than the thickness of the blanks to be operatedupon, while the slots 738 and 754 in the supporting arms 704 and 7 06permit the roll 618 to yieldupwardly as the blanks are introducedthereunder. y

In order that the upper roll 618 may be yyieldingly pressed against thesole-blank during the feeding of the latter across the cementapplyingroll 620, the sleeves 736 and 7 52 are acted upon by vsprings 758 and760, respectively. The spring 758 is seated within a recess 762 formedat the upper end of the arm 704, its lower end bearing against atransverse member 764, which connects the two sleeves 736 and partiallyencloses the upper gear 740. The upper end of the spring 760 is seatedwithin a recess formed at the upper ond of the arm 706, its lower endbearing against the sleeve 752. To adapt the stud 7 50 to be withdrawn'Vfrom the roll 618, the stud is provided with a nurled head. Abayonet-joint connection 768 between the stud `750 and the sleeve 752limits the outward sliding movement of the stud and permits the latterto be locked in its inner or rollsupporting position. To insurealinement of the shaft 734 and the stud 750, a verticaly spring 758 andthrough an aperture at the extremity of the recess 762. A nut 772,threaded upon the upper end of the rod 770, hears against the top of thearm 704 and may fl be turned to vary the normal elevation of thebearing-sleeve 736, and consequently of the shaft 734. Secured to theouter end of the driving shaft 714 is a beveled pinion 774, whichengages a beveled pinion 776 secured to the upper end of a shaft 778.This shaft 778 is so rotated from some source of power that thecement-rolls are driven continuously while the machine is in use. 4

Cement is supplied to the pockets 712 in the ribbed faces of the lowerroll 620 through a distributing device supplied' from a cementreservoir7 95. The distributing -device is illustrated in Figs. 1, 6 and 7, andcomprises an elongated head or nozzle 7 96, which is arrange-d at oneside of the applying roll 620 and is rigidly secured at one end to abracket 797 'depending from the member 704. The head 796 is providedwith a longitudinal bore 798 having a series of outlet-ports 799terminating 1n a concave face 800 at one side of the head. The curvatureof the face 800 corresponds to that of the roll 620. This face extendshorizontally throughout the length of the roll 620, and is arrangedclosely adjacent the upper edge faces of the ribs thereon. Thedistributing head 796 is connected by means of a pipe or conduit 802with the cement-reservoir 795. Two. of these pipes are illustrated forconnection to plural coating apparatus', but one of which appearsherein.` -V

` To p reventwaste of the cement, it is supplied to the roll 620 onlyduring such time as a sole-blank is being fed thereto.

by means of a valve. which is operated in timed relation with themovements of the feed-table 616. The valve comprises a tube 803, whichfits closely within the bore 798 in the head, and through which thecement is caused to flow. The valve-tube 803 is provided with a seriesof outlet-ports 804 adapted to register with the ports 799 in the head.The tube 803 may be oscillated to bring the ports 804 alternately intoand out of registry with the ports 799, thereby causing an intermittentflow of cement from the head to the roll. The oscillatory movement ofthe valvetube 803 is derived from the cam-disk 662, which actuates thefeed-table 616.` To this end, the valve-tube 803 is connected, in thefollowing manner, with the cam-lever 684, actuated by the cam-disk. 'Asshown in Fig. 1` an arm805 is rigidly secured to one end 'of thevalve-tube 8.03, and is connected by a link 806 with oneend of anarm;807 which is, in turn, rigidly secured to the outer end of arock-shaft 808. The rock-shaft 808 is j ournaled in a bearing 809rigidly supported by p To this, end, the 'outlet-port 799 in thedistributinghead 796 is adapted to be opened and closedv which pivotallyconnects the cam-lever 684 with the link 682. With this construction, asthe cam-lever 684 is swung toward the right, viewing Fig. 1, to slidethe feed-table (S16 toward the cement-applying rolls for the purpose ofintroducing a sole-blank therebetween, the valve 803 will be opened topermit a ow of cement to the lower roll 620. When the cam-lever 684ismoved in the opposite direction to carry the feed-table away from therolls. the valve 803 is closed to shut off the supplyn of cement.

To permit adjustment of the amount of cement supplied to the roll 620when the valve 803 is opened, the arm 805 is provided at its outer endwith a longitudinal slot 812 adapted to receive one end of a stud 813,upon the opposite end of which the link 806 is pivoted. Adjusting means,such as a screw 814, may be employed for -shifting the position of thestud 813 in the slot. With this construction, relative angular positionsof the link 806 and the arm 805 may be so adiusted that the ports 7 99and 804 will not be brought'completely into registry with each otherwhen the valve 803 is opened. In this 796 is more irmly held againstmovement.

The arm 815 may b e swung upwardly to disenga-ge the notch therein fromthe extremity of the valve-tube 803 to permit the removal of the rolls618 and 620 or of the valve 803.

As best shown in Fig. 5, the cement-reservoir 795 comprises acylindrical receptacleV 817 for cement. To maintain the cement in thereceptacle 817 at the requisite temperature to insure its free How, thereceptacle is enclosed within a hot-water tank 818 supported by bracketssecured to the frame. The tank comprises a cylindrical casing of agreater diameter than the cement-receptacle. The receptacle is supportedby a pair of bosses 819 projecting from it and being seated withinsockets formed in a pair of bosses 820 rising from the bottom of thetank. The space between the bottom walls and the cylindrical side wallsof the receptacle. and tank is filled with water, and a gage 821 may beprovided at the side of the tank to indicate the water level. Thetank,which may be conveniently filled through a cup 822, has at its upper enda circular opening of a diameter suiciently large to permit the removalof the cement-receptacle. This taarten grooves 827 yadapted to receivethe -ilange` 824. After the cover 823 has been placed upon the tank,with the lugs 825 projecting.-

through the notches 826, the cover is turned., thus moving the lugs 825out of registry with the notches and bringing the grooves 827 intoengagement` with the liange 824. The cement-receptacle 817 is filledthrough a circular opening in its top, which is normally closed by aremovable cover 828. rllhe cover 828 is kept closed, and thereceptacle'817 is prevented from rising, under the iniiuence of itsbuoyancy in the water-tank 818, by means of a screw 830, which isthreaded vertically `through the 'central portion of the cover 823, thelower end of this screw being seated in a central recess in the cover828. The screw 830 is provided with a hand-wheel 831, by means of whichit may be readily turned to securely hold the cement-receptacle againstthe bottom of the tank, and the cover 828 against the top of thereceptacle. The screw 830 serves also to lock the flanges 825 againstthe under side of the flange 824, thus securely holding the cover 823 inclosed position,

To :facilitate the lfree How of the cement through the conduits 802,means is provided for applying pressure to the cement within thereceptacle by an air-pump 832 mounted upon the hand-wheel 831 in axialalinement with the screw 830. rlihe interior of the pump 832 isconnected with the interior of the cement-receptacle by means of anairpassage 833 extending axially through the screw. At the lowerl end ofthe screw, the air-passage communicates with a central opening 834 inthecover 828. To prevent leakage of air when the operated, a gasket 835is interposed between the lower end of the screw 830 and the base of therecess in the cover 828 which is entered by Vsaid screw. A valve 836prevents outward leakage of air from the cementreceptacle.

Cement iows from the receptacle 817 into a central opening 838 in thebase of the reservoir, the flow bein controlled by a normally open valve839. eading from the opening 838 are two radiating passages 840, whichare inclined slightly downward. These passages .840 terminate severallyat the lower faces ofthe bosses 819 on the bottom of the receptacle, andcommunicate with -vertical pump 832 is being assages 841 in a pair ofvalve-casings 842 epending from the base of the Water-tank 818, eachvertical passage 841 terminating at its upper end in the base-of therecess in the respective boss 820. To prevent leakage of cement at.I thejunctions of the passages 840 and the passages 841, a gasket) 843 isinterposed between the base of the recess'in each boss 820 and thelendface of the corresponding boss 819. The passages 841 are severallyconnected at their lower ends by means of a coupling device 844 with theupper ends of conduits 802. In the present instance, but one of theseconduits is in use, this leading to the cement-supply valve 803. Thevalvecasings 842 are provided with manually operable valves 845 forshutting oli' the flow of each cement-conduit 802 is arranged betweentwosimilar conduit-s 848 (Figs. 1 and 5), through which a circulation o hotwater is maintained.Y The ends of the conduits 848 remote from thewater-tank are severally lconnectedto the opposite ends of a passage 849(Fig. 7) in the distributin -head 796, this passage extending horizontaly back and forth through Athe head at one side of the valve or tube 803.

The upper end of one of the hot-water conduits 848 of each pair isconnected through its coupling device 844 wit-h the lower extremity of apassage 850, which extends uplwardly through the correspondinglvalvecasing 842 and communicates with the bottom of the tank 818. Theupper extremity of the other conduit- 848 of each pair is connected, bymeans of the coupling devicejust referred to, with a second passage 851in the valve-casing, and communicates at its upper extremity with thelower end of a standpi e 852. The st-andpipe 852 rises within t e spacebetween the receptacle and the tank to a point somewhat below the normalwaterlevel and is open at its upper end.' Manually operable valves 853are provided in the assages 850 and 851, in each of the valve-casings842, by means of which the circulation of the heating water` may be shutoil.

The distributing head 796 is adapted to be heated by means of anelectrical heating unit, which may be inserted in a longitudinal recess854 (Figs. 6 and 7), which extends throughout the length of the headimmediately below the valve-tube 803. vThe conduits the distributinghead, the temperature of the water will be raised by theheat derivedfrom the heating unit in the recess 854, in addition to that from theunits 846, thus increasing the circulation throu h the conduits 848,this circulation being in t e direction 1ndicated by the arrows in Fi 5.It will be seen that the temperature o the cement, as it is applied bythe distributing head to the roll 620, will be maintained. by means ofthe heat derived directly from the heatin unit within the recess 854, aswell as from t e hot water circulating through the passa es 849. Thesource of heat at 854 may e uti 'zed at such timesas when iirst startingthe machine in operation. Its continued use might have a too greatdrying effect upon the cement and` clog t e delivery device.

It is desirable that means be provided whereby, when thecement-receptacle 817 is being inserted within the tank 818, saidreceptacle may be radily positioned, so that the bosses 819 carriedthereby will enter the recesses in the bosses 820 at the bottom of thetank. Accordingly, positioning devices are provided, comprising aplurality of Vertical guide-rods 856, which are secured to the innerface .of the side wall of the tank, as shown in Figs. 5 and 8, and aplurality of co-operatino' guide-blocks 857, which project outwardly romthe side walls of the rece tacle adjacent its upper and lower ends. T eguide-rods 856 are adapted to be engaged by V-shaped positioning notches858 formed in the outer faces of the guide-blocks 857. By

turning the receptacle until the notches are in engagement with thelrods, the bosses 819 will be brought into alinement with the recesses inthe bosses 820. The rods both act as guides and provide lateral supportfor the receptacle.

When removing the cement-receptacle from the water-tank for the purposeof refilling the former, it is desirable to shut off communicationbetween the interior ofthe receptacle and the central passage 838 in thebottom thereof by closing the valve 839, thus preventing the waterwithin the tank 818 from rising into the interior' of the receptacle. Asshown, the valve 839 comprises a sleeve 859, which is screw-threadedinto a boss 860 rising centrall from the bottom of the receptacle. Theower end of the sleeve communicates with the opening 838. A shortdistance above the lower end of the sleeve, four radial passages 861connect its interior with the interior of the receptacle. The.screw-threaded portion of the sleeve extends just above the radiatingpassages 861, and has an annular flange 862 formed above said threadedportion. By turning the sleeve by means of a handle at its upperextremity, the passages 861 may be brought below the upper end of theboss860, and the shoulder formed by the lower side of the flange 862tightly pressed against the upper end of said boss. In this tank and isthreaded into a boss 864 de endin from the lbottom of the receptacle.oosemng the screw permits the removal ofthe receptacle. Washers ma beprovided for preventing leakage of t water around the n screw.

The receiving table 622 (Figs. 1 and 2), to which the coated blanks aredelivered b the rolls 618 and 620, comprises a horizonte rectangularplate mounted to slide longitudinally u on a pair of parallel guide-ribs865 ris'- ing rom a bracket 866 carried by the frame. The table 622 isprovided with flanges 867 depending from its lateral edge-portions,

. which engage the outer edges of the guideribs 865, and the flan es 867have inwardly turned ribs 868, whic`l project beneath the guide-ribs 865to prevent upward displacement of the table. The table 622 is normallylocated with its rear extremity close to the rolls, and is moved awayfrom them to withdraw the heel-ends of the sole-blanks suiiciently fromthe positions in which they are delivered to permit said blanksto befreelyv lifted vertically, without being bent downward at the heel-ends.To accomplish this, the receiving table is connected by means of a link869 with any transferring orfother mechanism with the movements of whichit is desired to synchronize those of the table.

-To insure that'the blanks deliveredby the cementing rolls 618 and 620sto upon the table 622 in the correct position or transfer therefrom,there is associated with vthe table a locating armor stop-abutment 1001(Fig. 1). This abutment is pivoted at 1002 at the outer side of itstable, and is normally held out of the path of the transferringmechanism by 'a spring 1004 connecting the outer extremity of the armbeyond the pivotal point with a pin 1006 pro'ecting from the side of thetable. Mounte upon a bracket 1008 risin from a 'portion of the frame isa horizonta rod 1010 situated in alinement with the portion of the arm1001 to which the spring is attached. When the table is in its inner orreceiving position, ad'acent the rolls 618 and 620, the end of the ro-1010 contacts with the arm, swinging it about its ivot against thetension of the spring to ho d it in its active position across thetable.. At this time, a

curved portion 1012 of the arm lies in theA The rod 1010 is preferablyarranged to move wso piece delivered b Athe rolls. That is, just as theheel-end of t e piece has passed the bite i of therolls, the toe-endwill `contact with the stop-portion 1012, preventing the piece fromwbeing fed past the chosen position. Then, as the table moves over therolls in preparation for the engagement of the blank bythe transferringmechanism, the extremity of the arm 1001 leaves the, end of the rod1010, permitting the former to be drawn to one side by its spring 1004.-out of the path of such mechanism, this being as is illustrated in Fig.1.

To outline the operation of the apparatus, the table 616 is initselevated relation, ]ust below the magazine58. At the same time, thetable 622 has its inner end close to and substantially in the samehorizontal plane as the bite ofthe rolls 618 and 620. In thesepositions, the tables are temporarily held, awaiting the beginning of anoperating cycle. The separator devices'274 being operated, a singleinsole-blank is released from the magazine, falling on the table 616with itsA toe-end projecting from the extremity of the table toward therolls. Now the table descends until the blank is on the level of thebite of the rolls, and then is advanced horizontally to present theoverhanging end of the blank to the rolls. These, in their rotation,draw it between them, the upper or pressure-roll 618 forcing the iecedown upon the lower or cement-applying roll 620. Ce-

\ ment from the receptacle 817, heated by the or outward movement of thetable. way, by regulating the extent to which the water within the tank818 and by that in the pipes 848 on each side ofone of thecementdelivery pipe 802, flows to the distributing' head 796. As thetable 616 starts forward with the blank, the valve 803, in which thepipe 802 terminates, is opened by its connection to the table-actuatingmechanism, and

permits the cement to flow through the passages 'l' 99 to the surface ofthe roll 620, said valve being again closed upon the opposite In thisvalve opens by adJustment of the screw 814:, the supply of cement may bemade sucient without danger of flooding. From the rolls, the coatedblank passes upon the receiving table 622 against the locating portion1012 of the lever 1001, being thus positioned upon the table in theproper relation for engagement by transferring means. The blank havingbeen delivered and located in this way, the table 622 travels away from'the rolls to its outer position, `where the heel-end of the blank iscompletely` free from the rolls, so that its-verticalmovement will notbe interfered with. At the same time,'the lever 1001, released from itscontact withv the rod `10,10, is restored by its spring to its normalposition clear of the blank. This, with. the return of thedelivering-table 616 to its initial location beneath the magazine,completes the cycle of the apparatus. v
